How to make a Big whirlpool

[Rio.Dominia]

Hey guys.

 

I‘m tried to make a Big whirlpool in this days      First  I make the vortex force in Sop  .  then in the DOP I use volume source to use the sop velocity.   But finally  the effects looks so terrible

 

So ,  please anyone can help me  Just make a real vortex force to help me .

 

Thanks so much

[Hello world]

you can try to use cross product in vops and plug it in normals and use it as a vel
